Physical address in the 8086/8088 is {Selected Segment Register} * 16 + {Effective Offset Address}. It is a 20-bit address
.
It is mightily referring to Microprocessor 8086 . I think you saw "8086 microprocessor". The 8086 is nothing it indicates the number of microprocessor same as Digital or analog ic's . 8086 microprocessor has 20 Address buses and 8 data buses which has 1 Mb inbuilt memory for performing several type of airthmatical and logical operation.
segment is for converting physical address to logical address , here on taking 8086 microprocessor as example, we have 20 address lines but it is capable of taking only 16 address lines.... so to convert that 20 into 16 segment is used....
for demultiplexing address/data bus
Its 16bit microprocessor,and-> the 8086 has a 16bit databus 20bit address bus-> the intel 8086,is designed to operate in two modes namely(1) minimum mode(2) maximum mode
The 8086 microprocessor has 40 pins.
The 8086 Microprocessor operate to require frequency that is provided by clock generator to 8086 Microprocessor and also Synchronization various component of 8086.
queue of 8086 microprocessor is 6 bits
The Instruction Pointer (IP) in an 8086 microprocessor contains the address of the next instruction to be executed. The processor uses IP to request memory data from the Bus Interface Unit, and then increments it by the size of the instruction.
The 8086/8088 microprocessor has a 20 bit address bus, so the number of memory locations it can address is 220 or 1,048,576.
Pins 1 and 20 in the 8086 microprocessor are (both) power and signal ground (GND).
it is a 16 bit microprocessor & it has 40 pin .
Physical addressing in the 8086 microprocessor refers to the method by which the CPU accesses memory locations using a combination of segment and offset addresses. The 8086 employs a segmented memory model, where memory is divided into segments, and each segment has a base address. The physical address is calculated by shifting the segment address left by 4 bits and adding the offset address, resulting in a 20-bit physical address space that allows the processor to access up to 1 MB of memory. This system enables more efficient memory management and allows programs to use memory in a modular way.
